NEW QUESTION # 36
Which of the following activities are part of the development lifecycle using SAP HANA extended application services, advanced model (XS advanced)?
There are 2 correct answers to this question.
- A. Activate artifacts via _SYS_REPO.
- B. Store the source in the SAP HANA repository.
- C. Export the project as an MTA archive.
- D. Create an MTA project.
Answer: C,D
Explanation:
The development lifecycle using SAP HANA extended application services, advanced model (XS advanced) involves the following activities12:
* Create an MTA project: An MTA project is a container for the source code and configuration files of a multi-target application (MTA), which is a modular and scalable application that runs on the XS advanced application server. You can create an MTA project using the SAP Web IDE for SAP HANA, which is a web-based development environment that provides tools and templates for developing MTA components, such as database modules, Node.js modules, HTML5 modules, and Java modules. You can also use the command-line interface (CLI) of the Cloud MTA Build Tool (MBT) to create an MTA project from scratch or from an existing MTA archive.
* Export the project as an MTA archive: An MTA archive is a deployable package that contains the compiled and packaged MTA components, along with the MTA descriptor file (mta.yaml) and the MTA metadata file (MANIFEST.MF). You can export the MTA project as an MTA archive using the SAP Web IDE for SAP HANA, which automatically builds and validates the MTA components and generates the MTA archive. You can also use the CLI of the MBT to build the MTA archive from the MTA project source files.
* Deploy the MTA archive: To deploy the MTA archive, you can use the XS CLI, which is a command-line tool that allows you to interact with the XS advanced application server and perform various tasks, such as creating organizations and spaces, managing users and roles, and deploying and undeploying MTA archives. You can also use the SAP HANA cockpit, which is a web-based administration and monitoring tool that provides a graphical interface for deploying and managing MTA archives.
The other options are not correct because they are not part of the development lifecycle using XS advanced.
Activating artifacts via _SYS_REPO and storing the source in the SAP HANA repository are activities that are related to the SAP HANA extended application services, classic model (XS classic), which is a deprecated development and runtime environment that uses the SAP HANA repository as a central storage for source code and metadata. XS classic is not compatible with XS advanced, and it is not recommended for new development projects3. References:

NEW QUESTION # 37
You need to check user input data in your OData request. Which exit type do you use? Please choose the correct answer.
- A. Validation
- B. Consistency
- C. Modification
- D. Verification
Answer: A
Explanation:
To check user input data in your OData request, you need to use the Validation exit type. The Validation exit type is a custom exit that allows you to perform validation of input data and data consistency checks before, after, or during the change operation, or before or after the commit operation. You can specify a maximum of four validation exits per change operation; the exit is registered for the corresponding event with the respective keyword: "before", "after", "precommit" or "postcommit". The validation exit is executed as an SQLScript procedure with a specific signature, and it can raise an error if the input data does not meet the validation criteria1.
The other options, Consistency, Modification, and Verification, are not exit types that you can use to check user input data in your OData request. Consistency is not an exit type, but a property that you can set in the OData service definition to enable or disable the consistency check for the change operations. The consistency check ensures that the data in the database is consistent with the data in the request payload2. Modification is an exit type that allows you to define custom logic to create, update, or delete an entry in an entity set. If a modification exit is specified, it is executed instead of the generic actions provided by the OData infrastructure1. Verification is not an exit type, but a process that you can perform to ensure that the OData service definition is valid and can be activated without errors3.

NEW QUESTION # 40
What are the characteristics of the calculation view of type "SQL Access Only"? There are 2 correct answers to this question.
- A. Can be directly used for multidimensional analysis
- B. Can be directly used as modelled data source for another view
- C. Can be direct y accessed via SQL
- D. Can be directly exposed to all client tools
Answer: B,C
Explanation:
A calculation view of type "SQL Access Only" is a calculation view that is not visible to the reporting tools and does not support multidimensional reporting. However, it can be directly accessed via SQL and used as a modelled data source for another view. This type of calculation view is useful for scenarios where you want to perform complex calculations or transformations on the data, but do not need to expose the result to the end users or analytical applications. You can use the SQL Access Only calculation view as an intermediate step in your data modelling process, and then use another calculation view with data category Cube or Dimension to provide the final output for reporting or analysis. The other options are incorrect because a calculation view of type "SQL Access Only" cannot be directly exposed to all client tools or used for multidimensional analysis.
These features are only available for calculation views with data category Cube or Dimension. References:

NEW QUESTION # 41
Which artifacts do you define in the persistence model to access objects in an external SAP HANA Deployment Infrastructure container? Please choose the correct answer.
- A. Imports
- B. Synonyms
- C. Procedures
- D. Views
Answer: B
Explanation:
To access objects in an external SAP HANA Deployment Infrastructure (HDI) container, you need to define synonyms in the persistence model. Synonyms are design-time artifacts that provide a logical name and a reference to an object in another schema or HDI container. Synonyms allow you to access the data and functionality of the external objects without granting direct privileges or using fully qualified names1. Synonyms can be created for tables, views, procedures, functions, and other database objects2.
The other options, views, imports, and procedures, are not artifacts that can be defined in the persistence model to access objects in an external HDI container. Views are artifacts that define a logical data model based on one or more tables or other views. Views can be used to query data from different sources, but they do not provide a reference to an external object3. Imports are artifacts that allow you to import another CDS entity or a database table into the current CDS entity, and use its columns as part of the projection list. Imports can be used to reuse data definitions, but they do not provide a reference to an external object either4. Procedures are artifacts that define a set of SQL statements that can be executed as a unit. Procedures can be used to implement complex logic and calculations, but they do not provide a reference to an external object either5.

NEW QUESTION # 44
Which OData capacity do you use when you need to restrict the number or selection of exposed columns?
Please choose the correct answer.
- A. Aggregation
- B. Key specification
- C. Parameter entity sets
- D. Property projection
Answer: D
Explanation:
Property projection is an OData capability that allows you to restrict the number or selection of exposed columns in an OData service. Property projection is achieved by using the $select query option, which specifies a subset of properties to be included in the response. The $select query option can be applied to a single entity, a collection of entities, or a complex type. Property projection can be used to reduce the payload size and improve the performance of the OData service.
For example, suppose you have an OData service that exposes a Products entity set with the following properties: ID, Name, Category, Price, and Description. If you want to restrict the number or selection of exposed columns to only ID and Name, you can use the $select query option as follows:
GET /Products?$select=ID,Name
The result is: { "@odata.context": "$metadata#Products(ID,Name)", "value": [ { "ID": 1, "Name": "Laptop" }, { "ID": 2, "Name": "Mouse" }, { "ID": 3, "Name": "Keyboard" } ] }
The following OData capabilities are not used to restrict the number or selection of exposed columns, but for other purposes:
* Parameter entity sets: Parameter entity sets are a way to define entity sets that require one or more parameters to be specified in the request. Parameter entity sets can be used to implement function imports or actions that return a collection of entities. Parameter entity sets can also be used to filter or sort the results based on the parameters.
* Aggregation: Aggregation is a way to apply aggregate functions, such as sum, count, min, max, or average, to the properties of an entity set or a complex type. Aggregation can be used to perform calculations or analysis on the data. Aggregation is achieved by using the $apply query option, which specifies a transformation pipeline with various operators, such as groupby, aggregate, filter, or order by.
* Key specification: Key specification is a way to define the key properties of an entity type, which uniquely identify an entity instance within an entity set. Key specification is part of the entity type definition in the metadata document of the OData service. Key specification can be used to retrieve a single entity by its key values.

NEW QUESTION # 45
What are the issue categories that SQL Script Code Analyser scans for? There are 3 correct answers to this question.
- A. Privileges
- B. Performance
- C. Business logic
- D. Security
- E. Consistency
Answer: B,D,E
Explanation:
The SQL Script Code Analyser is a tool that scans SQL Script code for potential issues and provides suggestions for improvement. The tool can be accessed from the SAP Web IDE for SAP HANA or from the SAP HANA database explorer. The tool scans for issues in the following categories:
* Performance: This category covers issues that may affect the execution time or resource consumption of the SQL Script code, such as inefficient joins, missing indexes, unnecessary data transfers, etc. The tool provides recommendations for optimizing the code, such as using parallel processing, avoiding nested loops, using table variables, etc.
* Security: This category covers issues that may expose the SQL Script code to security risks, such as SQL injection, privilege escalation, data leakage, etc. The tool provides recommendations for securing the code, such as using parameterized queries, escaping literals, applying proper authorization checks, etc.
* Consistency: This category covers issues that may affect the readability, maintainability, or portability of the SQL Script code, such as coding style, naming conventions, documentation, compatibility, etc.
* The tool provides recommendations for improving the code quality, such as using consistent indentation, avoiding hard-coded values, adding comments, following best practices, etc.
The other options are incorrect because privileges and business logic are not issue categories that the SQL Script Code Analyser scans for. Privileges are handled by the SAP HANA Deployment Infrastructure framework, which automatically grants the necessary privileges to the technical users and roles that access the HDI container objects. Business logic is the domain-specific logic that defines the functionality and behavior of the SQL Script code, and it is not within the scope of the tool to verify or validate it. References:

NEW QUESTION # 48
Which activities do you perform on an application in the SAP HANA XS Advanced Cockpit? There are 2 correct answers to this question.
- A. Start, stop, and restart applications.
- B. Display HDI container content.
- C. Monitor applications assigned to the current space.
- D. Deploy applications to SAP Cloud Platform.
Answer: A,C
Explanation:
The SAP HANA XS Advanced Cockpit is a web-based administration tool that allows you to manage the XS Advanced runtime environment, such as organizations, spaces, applications, services, and users. The XS Advanced Cockpit provides a graphical user interface that is similar to the SAP Cloud Platform Cockpit, to provide a consistent user experience in cloud and on-premise. The XS Advanced Cockpit is available for SAP HANA 2.0 SPS03 and later releases, and it replaces the deprecated XS Advanced Administration Tools.
One of the activities that you can perform on an application in the XS Advanced Cockpit is to monitor the applications assigned to the current space. A space is a logical grouping of applications and services that share a common development and runtime environment. Each space belongs to an organization, which is a collection of users and spaces that share a common quota of resources. You can use the XS Advanced Cockpit to view the list of applications deployed in a particular space, and see their status, instances, memory usage, disk usage, and bound services. You can also filter, sort, and search the applications by name, status, or type.
You can also drill down into the details of each application, such as logs, events, environment variables, routes, and service bindings.
Another activity that you can perform on an application in the XS Advanced Cockpit is to start, stop, and restart the applications. You can use the XS Advanced Cockpit to control the lifecycle of the applications deployed in a space, such as starting an application that is stopped, stopping an application that is running, or restarting an application that is experiencing issues. You can also scale the applications by changing the number of instances or the memory and disk quota allocated to each instance. You can also delete the applications that are no longer needed.
The other options are incorrect because they are not activities that you can perform on an application in the XS Advanced Cockpit. You cannot deploy applications to SAP Cloud Platform from the XS Advanced Cockpit, as the XS Advanced Cockpit is only for managing the XS Advanced runtime environment on SAP HANA. To deploy applications to SAP Cloud Platform, you need to use the SAP Cloud Platform Cockpit or the Cloud Foundry Command Line Interface (CF CLI). You also cannot display the HDI container content from the XS Advanced Cockpit, as the HDI container is a database object that is not directly related to the application. To display the HDI container content, you need to use the SAP HANA Database Explorer or the SAP Web IDE for SAP HANA. References:

NEW QUESTION # 55
Which of the following can be used when implementing transaction management logic in SQLScript using savepoints? Note: There are 3 correct answers to this question.
- A. Savepoint
- B. Reverse savepoint
- C. Alter system savepoint
- D. Rollback to savepoint
- E. Release savepoint
Answer: A,D,E
Explanation:
According to the SAP HANA SQLScript Reference, the following statements can be used when implementing transaction management logic in SQLScript using savepoints:
* Savepoint: Creates a savepoint with a specified name within the current transaction. A savepoint marks a point in the transaction that can be rolled back to without affecting the rest of the transaction. For example, SAVEPOINT sp1;
* Rollback to savepoint: Rolls back the current transaction to the specified savepoint. All changes made after the savepoint are undone, but the transaction remains active. For example, ROLLBACK TO SAVEPOINT sp1;
* Release savepoint: Releases the specified savepoint and all subsequent savepoints. The released savepoints are no longer valid and cannot be rolled back to. For example, RELEASE SAVEPOINT sp1; The other options are incorrect, because:
* Reverse savepoint is not a valid statement in SQLScript. There is no such statement in the SAP HANA
* SQLScript Reference.
* Alter system savepoint is not a statement that can be used in SQLScript, but a statement that can be used in SQL. It triggers a savepoint operation for the entire database system, not for a specific transaction. It is used for administrative purposes, such as backup and recovery, not for transaction management logic.
References: SAP HANA SQLScript Reference, Chapter 6, Section 6.4.2, page 2111.
NEW QUESTION # 56
Which configuration file indicates the program that is executed upon start up when you run the Node.js module? Please choose the correct answer.
- A. package.json
- B. project.json
- C. mta.yaml
- D. server.js
Answer: A
Explanation:
The package.json file is the main configuration file for a Node.js module. It contains various metadata about the module, such as its name, version, dependencies, scripts, and main entry point. The main entry point is the program that is executed when the module is run or required by another module. By default, the main entry point is index.js, but it can be changed by specifying the main property in the package.json file12. For example, if the main property is set to "server.js", then the server.js file will be executed upon start up when the module is run.
The other options are not correct because:
* project.json: This is not a standard configuration file for Node.js modules. It may be used by some frameworks or tools, but it is not recognized by Node.js itself3.
* server.js: This is a common name for a file that contains the server logic for a Node.js module, but it is not a configuration file. It may be the main entry point for the module, but only if it is specified in the package.json file4.
* mta.yaml: This is a configuration file for multi-target applications (MTAs) in SAP HANA XS advanced model. It defines the modules, resources, and dependencies of an MTA, but it is not specific to Node.js modules5.
